Abstract (en)
Provided is a method for estimating a timing advance (TA) for each beam in a wireless communication system. First, a terminal transmits K preambles, to which K mutually different beam formings are applied, to a base station. The base station estimates the TA for each of the K received preambles. The base station can determine the final TA value of the terminal on the basis of the TAs estimated for each of the K preambles.
